Objectives

Summarize the existing knowledge of changes for a number of selected physical and biogeochemical variables and parameters, representative of the sea-ice ecosystem

Make a first tentative analysis of the effects of the predicted changes in the sea-ice horizon on the Arctic ecosystem.

To generate an accessible description of future changes in sea-ice biogeochemistry to focus scientific efforts, raise public awareness and facilitate climate policy making.

The workshop will aim to select appropriate variables and parameters, and provide evidence-based estimates of their changes within a pre-defined bandwidth of uncetainties. A two-step approach will be applied, which will involve quantifying the current status of the selected parameters/variables based on existing reviews and literature studies, before estimating changes for the selected paramters/variables over the coming decades, based on literature and modelling exercises.

Expected outcomes

A scientific position paper on expected changes in ecology and biogeochemistry of the Arctic sea-ice environment related to changes in sea-ice physics.

A comprehensible visualization diagram that illustrates expected changes in the Arctic sea-ice environment to serve policy makers and raise public awareness

Whereas the position paper and the diagram will have different audiences (scientists vs. the general public and policy makers), both will serve a similar goal. The summary exercise proposed here will clarify how climate change in the Arctic will impact the sea-ice biome, increasing our awareness of the specific sensitivity of Arctic sea-ice ecosystems and their exchanges with surrounding environments. For scientists, the position paper will serve as a guideline to focus future scientific efforts. At the same time, the diagram will allow scientists to better communicate climate change impacts to the general public.

Policymakers may use the synthesis to better define sustainable management of Arctic sea-ice related systems. An up-to date diagram may serve as a tool to illustrate not only the sensitivity of several individual parameters but also assess the resilience of the Arctic system as a whole.
